[Libguestfs] Why libguestfs guest exist exceptionally?



HI,

On a RHEL5 box, i tried to directly run guest which was issued by
libguestfs virt-xxx commands as below. But after some minutes, it
exited exceptionally.

Does anyone also hit the issue or know the reason?

connect: Connection timed out

Failed to connect to virtio-serial channel.

This is a fatal error and the appliance will now exit.

Usually this error is caused by either QEMU or the appliance
kernel not supporting the vmchannel method that the
libguestfs library chose to use.  Please run
'libguestfs-test-tool' and provide the complete, unedited
output to the libguestfs developers, either in a bug report
or on the libguestfs redhat com mailing list.
